RUBBER OVERSOLE.

Specification of Letters Patent.

Pat rented Tree. 1, 1914.

Application filed February a, 1914. Serial No. 818,550.

To all whom it ma concern:

Be it known that I, Ln ROY MALTBY, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain. new and useful Improvements in Rubber Oversoles, of which the following is a specification, reference being had to the accompany in drawings.

his invention relates to certain im rovements in oversoles and the object of t e in vention is to provide a device of this neral character having novel and improve means whereby the same may be conveniently and effectually engaged with the sole of a shoe.

Still another object of the invention resides in providing a device which is simple and durable in construction, inexpensive to manufacture and one which will be very efficient in use.

\Vith these and other objects in. view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claim.

In the accompanying drawing forming a part of this application, Figure 1 is a side elevation of an oversole constructed in accordance with my invention. Fig. 2 is a bottom plan view thereof. Fig. 3 is a fragmentary transverse section as seen on line 33, Fig. 1, and Fig. 4 is a similar view as seen on line H, Fig. 1..

In describing my invention. I. shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views and in which 1 indicates an oversole formed of rubber of the usual character provided for rubber oversoles, the same being provided alon the edges thereof with an upstanding an inwardly inclined sole engaging flange 2. This flange may be of any desired height to project above the sole and engage the lower portion of the upper, whereby to aid in the retention of said sole in place when applied to the sole of a shoe. As stated. this oversole 1 is formed of the usual rubber composition provided for use in connection with overshoes and the shank 3 of this sole is formed for the greater portion thereof of live rubber, indicated as 4.- This sole, with the shank thereon is of such a length as to permit the free edge of the shank portion to be spaced to m the heel seat when the com plete oversole is applied to use on a shoe.

The flange 2, formed on the edge of the sole 1, terminates substant ally at the junct on of the shank 3 with the sole proper and I have provided an improved means in connection with the shank for the securin of the latter in place on the shank of the s as, to which the some is to be applied. To this end, blocks formed of trxtile material are inserted in the live rubber 4,.hdjacent the rear edge thereof and along the side edges of the shank and mounted in these blocks 5, are the ends of a pair of u \vardl curved hook members 6 which are i, csi nm for engagement with the shank of tie sole of a shoe. When the oversole proper has been applied to the sole of a shoe and the books .7 suitably engaged with the shank of the sole of said shoe, this device will be securely held in place thereon.

The device so sized as to require stretch iug both lon itudinally and laterally in the application tiereof to use. Thus, in ap 1ymg the device after the sole of a shoe as hren roperly fitted in this ovcrsole, so that the ange projects over and above the sole of the shoe proper, it is necessary to stretch the device from the shank portion thereof rcarwardiy or longitudinally, such stretching being made possible view of the live rubber portion 4 thereof. After stretching the same longitudinally, it is necessary to stretch the same laterally also in order to permit the hooks 5 to be engaged with the nanovvest portion of the shank of the sole. In view of these conditions, it will be seen that after the application of the device to the sole, in a manner as described, the portion 4. funding to return to its initial or normai position, will draw the books (3 forwardly and imvardiy and cause the some to bind tightly against the shank of the sole of the shoe, thus securelv retaining the comp to oversoie in position on the shoe. This will admit of the use of this device for rough walking or for dancing purposes and,,in either instance, the use thereof will positively prevent the wearer from slipping as would be true under ordinary conditions.

From the foregoing it will be seen that I have provided a simple, inexpensive and efficient means for carrying out the objects of the invention and while I have particulai'ly described the elernents best adapted to perform the finn'rtie'ns set forth, it is obvious that various changes in form, proportion and in the minor details of construction may he resorted to without departing from-the s irit 0 sacrificing any of the principles of t 1e invention.

Having thus described this What I claim is;-

An over appliance for shoes comprising a half sole, :1 flange formed thereon adapted to grip the edges of the sole of the shoe, a laterally and longitudinally yielduhle shank invention,

provided for said sole, the longitudinal edges of uid shank having recesses formed therein and arranged in transverse alinement with rui'h other, blocks of textile mateiiul secured in the iecesses and hook members secured in the textile material adapted to engage the Shilnli of a shoe sole.

In testimony whereof I hereunto aiiix my signature in the piesenee of two witnesses.
